This invention relates to'hand tools, and

more particularly to a' tool of this type provided with paralleloperating jaws. I have chosen to show a preferred embodnnent'of myinvention as applied to a tool for cr1mping metal tips upon the ends ofshoe-laces,

although it will be obvious that the principles of my invention may beapplied 'to similar tools usable for various purposes and provided withoperatingjaws of various vide improved means for connecting the jaws ofthe tool to thehandles and to further provide improved means forguiding. the jaws in their operative movements so that they willbemaintained in substantial parallelism. i j

A still further object of the invention-1s to provide an improved andsimple means for connecting the jaws of the tool to the handles so thatthey will be maintained in the proper'lateral'relation to each other;

A still further object of the invention 1s to provide jaws of a handtool of the character described with a plurality of cooperatingoperatingsurfaces, which may be used for various purposes. a i

To these and other ends-the invention consists in the novel features and'combinations of parts to be hereinafter described and claimed. a

are provided. The principles of thein'ventio'n will/be readily adaptableto working I jaws which are designed for variousxuses and are notrestricted to the precise form shown.

WILLIAM A. BERNARD, OF NEW HAVEN, CoNNEc'rICUnAssIGNoR TO THE .WiLLIAMThe tool shown is provided with the lever handles 10" and 11,;whichareQpreferabIy made of sheet metal or the like and are U- shaped incross-section to, provide a firm gripping surface for the hands of theoperatorj These lever handles ma be knurled, as shown in Fig. 1, ifdesired. The

handles are bifurcated at their forward ends ,to form the forked arms 12upon the-lever handle 10 and the forked arms 13 upon the. lever handle11. As shown more particularly in Fig. 4, it will be seen that one oftheforked portions of each of the levers is positioned between'the twoforked portions of the other lever and these two lever handles arepivoted together by the pivot pin 14. A coil spring 15 is wound aboutthe pivot pin 14 between the bifurcated portions of the lever handlesand the ends of this. spring. react against .the levers so, as to urgethe same to open position; The forked portions of the levers extendforwardly in advance of the pivot .14, the. two outside forked endsbeing so curved that the forked ends of one lever will lie insubstantial verticalsalignment with the ends of theother V lever, asshown in Figs- 3, 5 and 6. v I v The jaws which I have shown connected 1to the levers are designed for substantially parallel movement in adirection transverse to the longitudinal axis of thejtool. .These jawsare designated by thenumerals l6 and '17, respectively, andconsist of:two fiatlmembers whichare mounted for sliding move .ment on eachothertobring their cooperat mg surfaces into working relation. The jaws areprovided, respectively, with perforations 18 and 19, through which arepassed pins 22 and 23, thus pivotally connecting the jaws to leverhandles 10 and 11. As illustrated in the drawings, the jaws 16 and 17are extended longitudinally 'with respect to the is by providing themwith cooperating slots and pins to cause them to move in substantialparallelism. While pins, other .thanthe pivot. pins may be provided uponthe jaws and used for this purpose, I

have chosen to illustrate guide slots: 20 and 21, in the jaws 16 and17,. formed in transverse alignment with. and adapted to receive,respectively, the pivotpins 23 and 22, each of which passesthrough, theperforation in one jaw and the slot in the other jaw, so that commonmeans are providedgto pivot the jaws to the handles and to guide them intheir movements The jaws are thus guided in substantial parallelism bythe cooperating slots and pins, while the forked. ends of the leverswhich embrace the jawsupon each sijdexwill maintain them in; lateralcontactwith each other.

Each one of the jaws is, provided at one end with a returned portion.24-, whichis turned up to provide a seat 25, which is longitudinallydirected with respect tothe axis ofthe tool, while the opposite end, ofeach jawisprovided with aconcave surfaced forming. edge 26 which islongitudinally directed with respect to the axis of the tool and isdesigned to. cooperate with the seat or socket 25. The. returned portion24 causes the jaws to be shaped 'in the form of a J in longitudinalcross-section. Itwill, therefore-, benoted that each aw may be identicalwith the other in shape, location of slots and perforations,andcuttingnotches thereby decreasing the cost of manufacture, by requiringbut one[set of tools-for making same,

and that larger quantities may be made at one time. As shown in Fig. 5,thejaws when opened will occupy such a position relatively to each otherthat a substantial opening 27 will be provided above the sockets 25 topermit the insertion of the lace tip therethrough. The jaws may beprovided, if desired, at thefront edges thereof, with cooperatingcutting surfaces 28 and 29, which may be used in connection withtllt-llOOl described to sever the ends .of the laces. A hookor latch 10may be provided I to'hold the handlelevers in closed position.

In Fig. 7 is shown various steps in the operation of crimping a metaltip upon the end of a lace 81. The tips are usually sold in the formshown at 30 in this figure in which they are shown as partially roundedto presenta U-shaped cross-section.

The operation of the device is as follows: A lace is inserted within atip, as shown in the View at the left of Fig. 7, and the lace and. tipare then inserted through the opening 27 into the socket or seat formedat the end of one of the jaws. The jaws are then brought together,,asshown. in Fig. (i, and the resulting operation will be-the turning. ofthe tipinto the form shown in the two views at the right of Fig.7 andthe crimping or binding of the tip in this position. The socket 25 uponone of the jaws may be smaller than that providedv upon the other jaw soas to provide for the crimping of larger or smaller tips upon thelaces.

In some cases the laces will be foundto be longer than desired, andifjthis is. true, they can-be: cut oii'tothe desired length, by thecutting jaws 28. and 29, which are pro vided at the forward facesofthetwo jaws.

While I have shown and described a preferred embodiment of myinventiomin connection with a practical use for the same, it is to beunderstood that the same is not limited tothe exact form and usedescribed I againstthe action of aclam'p screw, A.

very effective and strong terminal is formed .upon; the stranded wirewhen this tool is used to crimp such a tip. about the strands, whichobviates, due to the close electrical contact obtained,the useof solderor the like.
